What is a normally closed magnetic switch?
A “normally closed” / “magnet closed” reed switch has a protrusion that hides a small biasing magnet. When a magnet is nearby, a gap inside a “normally open” / “magnet opened” reed switch closes, completing the circuit and causing the LED to light up. A nearby magnet turns the LED on.
What is a normally closed switch?
The normally closed switch remains closed in the static state and opens the circuit when it is activated. The normally open switch remains open in the static state and only completes the circuit when it is activated. This contrast also leads to different applications.
What are the symptoms of a bad reed switch?
Some of the problems you may encounter when using non-contact reed switches in position indication systems are switch set point drift, reed switch sensitivity, and unstable indication.
What is the difference between normally open and normally closed limit switch?
A “normally open” limit switch has its contacts open in its resting state, meaning no current flows until the switch is activated, whereas a “normally closed” limit switch has its contacts closed in its resting state, allowing current to flow until the switch activates and breaks the circuit; essentially, a normally open switch needs to be triggered to complete the circuit, while a normally closed switch needs to be triggered to interrupt the circuit.
